Question

A magazine reported the results of a random telephone poll commissioned by a television network. Of the 1445 men who responded, only 39 said that their most important measure of success was their work. Complete parts a through c

a) Estimate the percentage of all males who measure success primarily from their work. Use a 95% confidence interval. Don't forget to check the conditions first. to Type integers or decimals. Round to one decimal place as needed.) b) Some believe that few contemporary men judge their success primarily on work. Suppose we wished to conduct a hypothesis test to see if the fraction has fallen below the 6% mark. What does your confidence interval indicate? Explain. Choose the correct answer below. O A. Since 6% is not in the interval, there is strong evidence that fewer than 6% of all men use work as their primary measure of success. o B. Since 6% is in the interval, there is strong evidence that fewer than 6% of all men use work as their primary measure of success Since 6% is than 6% of all men use work as their primary measure of success. in the interval, there is strong evidence that more O D. Since 6% is not in the interval, there is strong evidence that more than 6% of all men use work as their primary measure of success. c) What is the level of significance of this test? Explain. The level of significance is a The test is a(n) Y est based on a

Explanation / Answer

The statistical software output for this problem is:

One sample proportion confidence interval:
p : Proportion of successes
Method: Standard-Wald

95% confidence interval results:

Hence,

a) 95% confidence interval will be:

(1.9%, 3.5%)

b) Option A is correct.

c) 0.05; left tailed; alternative hypothesis
